VIBES toolbox for MATLAB Experimental modelling // Dynamic Substructuring // Transfer Path Analysis

The VIBES toolbox for MATLAB offers unique capabilities for Experimental Modelling, Dynamic

Substructuring and Transfer Path Analysis. The latest scientific advancements in structural dynamics

have been implemented in an easy-to-use toolbox for MATLAB. The toolbox comprises a powerful

3D environment, allowing to pick and place your measurement instrumentation on CAD geometry.

The object-oriented workflow unlocks a wide range of Frequency Based Substructuring and TPA

methods, all accessible and adaptable from the command-line. Save time by automating repetitive

processes in simple scripts and generate plots conveniently using intuitive commands for data

selection. Create FEM-compatible ‘super-elements’ from FRF measurements using the Virtual Point

Transformation. Combine experimental component models, numerical models and operational data,

realising a truly hybrid approach to sound & vibration simulation. Import, manage and share your

results using the industry-standard ASAM-ODS format.

Fully integrated with MATLAB Object-oriented // Extendable classes // Independent from other toolboxes

The object-oriented toolbox provides well-designed classes and functions for analysis and simulation

of sound and vibrations. All data (time series, FRF spectra, etc.) and meta-data (channel description,

units, etc.) are kept neatly together, which simplifies and accelerates your way of working. This object-

based data management is the perfect solution to archive, retrieve and share data with your

colleagues that use a variety of tools / software. For the first time, one has the possibility to perform

complex substructuring and TPA operations simply by writing out their most basic formulas. The VIBES

toolbox assists you along the way and handles all the ‘bookkeeping’ automatically. A CAD-like 3D

experience as well as an audio playback service are offered to further improve your workflow.

Through the object-oriented structure of the toolbox, one is able to extend all classes, which allows

you to customise the VIBES toolbox for MATLAB. The implementation of custom version control,

routines, methods and algorithms etc. are all possible.

Dynamic Substructuring Analyse the dynamics of mechanical systems

Dynamic Substructuring (DS) has proven to be a powerful engineering

tool for a wide variety of industries. It allows a complex dynamic system

to be modelled and analysed as separate components. The components

may be coupled from either numerical (FEM) or experimental nature.

DS allows identification of local dynamic problems, as well as efficient local optimisation of the structure with respect to its assembly. It enables sharing and combining substructures from different suppliers and design groups.

Transfer Path Analysis Quantify and qualify structure-borne and airborne vibrations

Transfer Path Analysis (TPA) has been a valuable engineering tool for as

long as noise and vibrations of products have been of interest. A TPA

concerns a product's actively vibrating components (such as engines,

gearing systems or turbochargers) and the transmission of these

vibrations to the connected passive structures.

TPA is particularly useful when the actual vibrating mechanisms are too complex to model or measure directly, as it allows us to represent a source by forces and vibrations displayed at the interfaces with the passive side.

Experimental Modelling FE compatible models from measurements

A key factor in successful Dynamic Substructuring and Transfer Path

Analysis efforts, is proper coupling of component models. For a

complete and accurate model of the dynamics at the interface, both

translational and rotational degrees of freedom are required.

The Virtual Point Transformation allows the translation of measured

Frequency Response Functions in the vicinity of a coupling point to FRFs

with six degrees of freedom per coupling point, resulting in FE-

compatible models.
